Description
The four pieces of this hinged dissection have plastic tops glued to wooden bases. They can be arranged to form a triangle two ways.
This is model 4D in Wheeler's triangles in his list of decompositions of polygons.
A drawing of this model, dated January 4, 1932, is in 1979.3002.55, folder 1. It refers to Macaulay, Math. Gaz, 1915-1916, p. 382. Another drawing, marked D and also dated Janury 4, 1932 also shows this dissection. It is in 1979.3002.55, folder 2. There is a drawing in 1979.3002.50, dated November 21, 1931, that refers to a hinged model using this dissection - this model is larger than that drawing.
